The ``other evergreens'' of which the wreath may be principally made
include any plant which retains its greenness through all the seasons of
the year, such as laurel, ivy, yew, fir, and others. While plants other
than evergreens may be used in making the wreaths, such plants, whether
they are forest products cultivated plants, cannot be considered as part
of the required principal evergreen component of the wreath.
